Tempstar PTAC Thermostat Kit for TEB07K25SPA — Knob + Wall Thermostat | Ships Today

Overview

This is the genuine OEM PTAC thermostat assembly for the Tempstar TEB07K25SPA packaged terminal unit. The kit covers the wall thermostat (OEM 1058517) and its control knob (OEM 1058437), the low-voltage control that tells the unit when to call for heating or cooling. The thermostat reads room temperature and switches the 24V control circuit to the relays and compressor. When a PTAC thermostat fails, you'll see no response to setpoint changes, a unit that won't cycle on, continuous running, or a missing/cracked control knob that won't turn. Replacing it with the correct OEM part restores accurate temperature control and proper cycling.
